Just a few small observations, When adding a Visual Studio 2019 C++ solution to the IDE, the "Solution Items" folder (should be at the top rather than in alphabetical order in my opinion) This folder contains my .clang-format, .clang-tidy and CMakeLists.txt files).
Lastly - the icon used in VS (which has a '++' as opposed to the cube in SlickEdit) also contains both references and external dependencies containers that can be pretty handy at the project level. Not a big deal not to have these in SlickEdit though but perhaps food for thought.
Attached see the solution view compared side to side.
